MACHINE FOR COMBING FIBROUSMATERIALS.

SPECIFICATION forming part of Letters Patent No. 511,128, dated December19, 1893. Application filed August 30, 1892. Serial No. 444,580. (Nomodel.) Patented in England November 25, 1891, No. 20,509.

To all whom it may concern:

Be it known that we, GEORGE EDMUND DONISTHORPE, merchant, of 12 OatLane, and TAYLOR BURROWS, engineer," of 88 Upper Kennington Lane,London, England, subjects of the Queen of Great Britain, have invented aMachine for Oombing Fibrous Materials, (for which invention we haveobtained a patent in Great Britain, No. 20,509, dated November 25',1891,) of which the following is a specificatior.

Thisinvention relates to machinery or apparatus for combing more or lesscoarse fibrous materials such as wool, flax, tow and the'like andanalogous materials and the ob ject of our invention is to produce asimple and efii'ective machine to comb at a rapid speed and in a highlyeffective and economical manner such more or less coarse fibrousmaterial to eliminate the short fibers and impurities therefrom so as toobtain a high percentage of fiber of suitable length for textile fabricsin a very rapid manner.

Our present invention comprises certain features and characteristicparts-all of which will be hereinafter fully set forth and finallypointed out in the claims; and in order that our present invention maybe easily understood and readily carried into practice we will proceedto fully describe the same with reference to the drawings hereuntoannexed.

In the drawings, Figure l is a plan of our complete machine. Fig. I is aside elevation of the machine looking in the direction of the arrow 1Fig. 1. Fig. 3 is an end elevation looking in the direction of thearrows 2 Figs. 1 and 2. Fig. i is a side elevation of the carrier combformed of three bands. Fig. 5 is an end elevation on an enlarged scale,and Figs. 6, 7 and 8 are detailviews showing the manner and means ofcombing one end of the fibrous material as it is fed onto the carriercomb while the impurities, 85c, thus combed out remain behind in thefibrous material on the feed head in such a manner that the nip jaws (ontheir next approach) seize such impurities in the uncombed part of thenext tuft to be drawn out and deposit the same (i. e.,the impurities anduncombed part) entirely on the opposite side of the carrier comb to thedrawing oft device-while only clean or combed fiber lies in the teeth ofthe carrier and on the drawing on side thereof. Fig. 9 is a front viewof a part of the nacteur comb and Fig. 10 is an edge view of such comb.Fig. 11 is a detail view in elevation of the stroking appliance lookingin the direction of the arrow Fig.1. Fig. 12 is an edge view of Fig. 11in elevation looking in the direction of the arrow Fig. 11.

A is the carrier comb; B the drums or pulleys around which thecarrierAis caused to travel.

0 is the main driving shaft.

1) is the pin plate of the feed head.

E is the nip jaw.

F is the point where the fiber is drawn off out of the carrier comb A.

H is the drawing ofi band.

Us a trough to conduct the combed fiber or sliver across the machine anddown the chute K into the sliver can or vessel L. l

M is a cam to actuate the upright rods N connected to the tin plate D soas to cause the rise and fall thereof at the right moments.

P P are arms or rods loosely mounted on the axle 0 at one end and at theother carrying the fine comb or nacteur comb R- these arms P beingperfectly free to turn or pivot on O. I

S are the bars forming the grid between which bars the fibrous materialis drawn by the nip jaw E. See Figs. 6, 7 and S.

T are the pins on the pin plate D advantageously graded finer from leftto right.

U is the reciprocating arm (carrying the dabbing device, die.) fixed onthe axle O and oscillated by the lever arm V rigidly fixed on the axle Owhich arm V is actuated by the connecting rod W pivoted at W to a movingpart of the machine for actuating the nipping jaws E.

Any suitable system of cams and levers or other mechanism may be usedfor giving the desired vmotion to the nip jaws E (and also the arm U)and this will be easily understood and readily carried into practice byany person skilled in the art of building this character of machinery.

a a a are the individual bands composing the carrier comb A.

b is the combed end and c the uncombed end of the tufts of fiber as thesame are dabbed into the teeth of the carriercomb A by the dabbingdevice d on the arm U.

c is another arm mounted loosely on the axis 0 and resting on a crossbar f fixed by the arms f to Uwhile the outer end of e carries a bladeor bar g to nip the end I) of the tuft of fibrous material just beforethe dabbing device d descends to dab the tuft into the teeth of thetraveling carrier comb.

r is a brush on the arms or framef'carried by U to brush upward the endsof the fibrous material left projecting from the pin plate D ready forthe next advance of the nip jaw. t is an arm or blade also fixed on fextending below the brush 1' and serving to part the fibrous material asthe jaw E recedes.

i 2' are driven rollers for drawing the sliver out of the trough I.

k are a pair of driven rollers for drawing the impurities (or residuum)out of the teeth of the endless carrier comb A and thus cleaning same onits way round to the feed head.

Z is a chute down which the refuse, &c., are guided into a can or Vesselyto receive same.

m is a crank for actuating the stroking appliance 0.

p is the pressing plate for keeping the fibrous material pressed intothe teeth of the carrier comb A and insure the fiber being drawn throughthe teeth thereof.

The endless traveling carrier comb A is composed of three metal hands a(advantageously thin bands or ribbons of steel similar to band saws)traveling in a horizontal plane and having teeth or pins formed thereonintegrally therewith and in the case illustrated we have shown thistraveling endless carrier comb A composed of three such hands a see Fig.l=but we would remark that we do not limit ourselves to the number ofsuch hands a composing the carrier comb A.

The operation is as follows: The carrier comb A is caused to travelaround in a horizontal plane by passing around the drums or pulleysBwhich are revolved by any suitable train of wheels or mechanismactuated from the main driving shaft 0. The jaws E open and advancetoward the pin plate D and receive the protruding ends a of the fibrousmaterial and snap hold of the same (see Fig. 6) close up to-the pinplate D and at that moment the said plate D is in the raised positionand the pins T clear of the fibrous materialwhile the nacteur comb isalso raised up clear and out of the way of the jaws E. The jaws E thenbegin to recede from D and draw the whole-body of fibrous materialthrough the grid S about onehalf an inch or thereaboutwhereupon theplate Dsuddenly descends and pins T pass through the fibrous materialand(at the same moment the pin plate D drops down) the nacteur comb R alsodescends into the fibrous material just clear of the pin plate D andclose up to same-as in Fig. 7. The jaws E (continuing to retire) .nowcommence to tear out the tuft of fibrous material, one end being pulledthrough the comb R and then the bladet falls across the path of thefibrous material and helps to part the tuft from the main body and thejaws still retiring, the nip-blade g then falls and holds the combed endI) of the tuft see Fig. 8 or the nip blade g may be dispensed with. Thejaws E finally retire quite clear of the carrier comb A and thenopen andthe dabbing plates (or device) d fall and dab the tuft right down intothe teeth of the traveling carrier comb A and it passes along. The arm Uis then rapidly raised and as it returns carries up with it the arm eand nip blade g thereon-while the brush r brushes up the end 2 ready tobe seized by the jaws E on their next advance. Thepin plate D is thenraised and thereby raises the comb R as in Fig. 6 and the jaws E againadvance and snap hold of z and pull out (and thereby comb one end of)another tuft and so on continuously. The action of the nacteur comb orfine comb R descending into and through the fiber between the jaw E andthe holding plate D-immediately before the jaw E begins to pull out thetuft of fiber from the body of the fiber held by D-insures that the jawE draws the end (not held in said jaw) through this nacteur or fine combR and thus combs said free end and then deposits this tuft upon theteeth of the traveling carrier comb A (and so on) with theimpurities,&c., and uncombed part on one sideof the said carrier and the cleanedends on the opposite and drawing off side.

The introduction of the nacteur comb in the manner and for the purposesdescribed is a very important and essential point in our invention.

The tufts of fiber thus laid in the teeth of the carrier comb A arecarried along by said carrier (in the direction of the arrows 0c) obeingthe now uncombed end and b the combed end-until the combed end bis'seized at the point F by the drawing off endless apron or band H(revolved from the main shaft 0 in thedirection of the arrows h) bymeans of the gear Wheels 9, g, g g g and 9 or any other suitable trainof gearing, and the uncombed part 0 of the fiber is forcibly drawnthrough the teeth or fine pinson the carrier comb A thereby completingthe combing or cleaning of the respective tufts or lengths of fibrousmaterial and the resulting clean fiber or sliver is led across themachine in the guide trough I having power rollers i at the end thereofand through a chute K which de-' livers the combed fiber into the slivercan L or other suitable receptacle. It will thus be seen that the hereindescribed machine pulls out tufts from the bulk of the fibrous materialand in so doing cleans or combs one part thereof and deposits saidtufts, with the cleaned ends on one side of the traveling endless bandcomb, and the uncombed ends on the opposite side of the said endlessband comb, to i be afterward drawn through said band comb and socleaned. Thus itwill be band comb.

The addition of astroking appliance is very beneficial and advantageousand we have illustrated an appliance suitable for our purpose, viz:

misacrank or crank arm rotated by the bevel cog-wheel'm' which in itsturn is driven by the bevel cog-wheel m the spindle m of this latterbeing rotated by a pulley and belt thereon or by spur gear (this drivinggear not shown in the drawings). The outer end of the crank in ispivoted at o' to the stroking appliance o. This stroking appliance orrod 0 besides being pivoted to the outer end of the crank arm or has itsupper end passed through a slot much wider than itself forming aguideway in the head stock 0 of the upright 0 Thus the upper part of thestroking appliance or' red 0 while free to move up and down inthelongitudinal slot or guideway in the head stock 0 is of such alengththat the upper end of the rod 0 can never come below theguiding slot inthe head stock 0 by reason of the length from the top of the rod 0 tothe pivot 0 being greater than the most extreme distance that the pivot0 can 'move from the head stock 0 Thus it will be seen that on the crankat being revolved by the bevel gear wheels at m (or by any othersuitable mechanism) such crank arm acting in combination with theguide-way in thehead stock 0 causes the stroking appliance o to beraised up through the guide 0 and the lower end 0 will be raised clearof the teeth of the endless traveling band Cr, and will be passedbackward in the direction of the arrow 34 clear of such teeth and thefiber therein (see the middle position shown in dotted lines in Fig. 11)until at its rear-most position the crank We will cause said rod 0 todescend (see the rearmost position shown in dotted lines in Fig, 11)below the teeth on the carrier as and the fiber therein and then thefurther rotation of crank m will cause the rod 0 to sweep right alongfrom the said rearmost position to the position shown in full lines inFig. 11 at a much more rapid rate of travel than that of the carrier a.Thereby the fiber in the carrier a is stroked or swept forward so as topresent the same to the drawing-off device.

The tow or waste fiber or residuum left in or on the carrier comb A(after passing the point F) is lifted out or removed therefrom in anysuitable manner, so that the carrier comb may be always thoroughly cleanwhen it arrives under the feeding device.

13 is a compressor plate or device fixed over the carrier comb A andfitting down closely thereon or thereinbetween to prevent the fiber fromrising out over the top of the teeth of the carrier comb A while thesameis being stroked and especially while being drawn oft.
